covmmn PAPER BOX.

I Application filed June 4,

To all whom it may conceive:

Be it known that I, HARRY BRIDGMAN SMITH, a citizen of the UnitedStates, and resident of New York city, in'the county of Kings and Stateof New York, have invented certain new, and useful Improvements inCovered Paper Boxes, of which the following is a specification.

My present invention relates generally to the art of manufacturingcovered paper boxes and more particularly to boxes having multiply endwalls formed from folded and overlapped portions of the blank or blanksfrom which the box is made.

One object of the invention is to provide a covered paper box of the socalled multiply end wall type wherein the cover. paper is applied to thebox shell in a distinctly new way to the end that the strength andappearance of the box are improved and the method of manufacture greatlysimplified. Other more or less important objects will appear from thedetailed description to follow.

I am aware that paper boxes having multiply end walls are old in theart, and I am also aware that cover or wrapper blanks have been appliedto such boxes, but my present invention resides in a novel manner ofapplying the cover or wrapper blank to boxes of the multiply end walltype and wherein portions of the cover or wra per blank lie in betweenadjacent faces 0 the multiply end wall structure of the box.

Briefly and more specificall stated, the invention consists of a coverepaperbox, including a shell blank folded to box form and having multiplyend walls formed in part by corner laps and in part by end wings"constituting portions of the shell blank,

the said corner laps being arranged exte-- riorly of the end wings, anda cover blank applied to the box and having marginal edges thereofoverlying the marginal edges of the side walls as well as the foldedcorner laps with portions of said overlying marginal edges confinedbetween adjacent faces of the end wings and associated corner laps,

the said cover blank also having end wings folded to overlie the outerface and upper edge of each multiply end wall of the box with themarginal edge of each wing adhesively affixed to the inner face of itscompanion shell blank end wlng.

In order to enable others skilled 1n the Specification of LettersPatent.

art to understand, make and practise my said invention, I will proceedto describe a preferred embodiment thereof in connection with theaccompanying drawings, wherein- Figure 1 is a perspective viewillustrat- 1ng one type or construction of shell blank which I mayemploy in my improved box..

F g. 2 is a perspective view of the said shell blankand a cover blankwith which it may beassociated. I

Fig. 3 is a perspective view of the shell and cover blanks combined toproduce what I have termed an assembly.

Figs. 4, 5, 6, 7 and 8 are perspective views illustrating the severalsteps or stages in the operation of folding the assembly into box formand, r b' Fig. 9 is a perspective view of the finished In the particulartype of box elected to illustrate the present invention, A designatesthe shell blank and B the cover or wrapper blank. The shell blank isusually made of heavy paper board stock such as commonly employed inthis art and B is made of relatively light paper, which may be plain ordecorated as desired.

The box shell blank A is scored or creased longitudinally andtransversely as shown to provide a body portion 1, and integral sidewings 2, and end wings 3. The side wings 2 are each provided with cornerlaps 4 at the ends of said wings, the corner laps forming extensions ofthe side wings. Blanks of this general type are common in the art and Ilay no claim thereto except when associated with a cover blank in themanner and to secure the results hereinafter stated.

'The cover blank B is cut in such a manner as to provide a body portion5 with integral side wings 6- and end wings 7 the side wlngs beingprovided at their ends with extensions 8 adapted to overlie andpartially cover the corner laps 4 of the shell blank in the mannerpresently to be described.

In making my improved box with the two blanks A and B above described, Iarrange the blanks in superposed and proper registration relation andthen inturn the marginal edges 9 of the cover blank over and afiix suchedges to the corresponding marginal edges of the side wings2 as well asthe marginal edges of the corner laps 4 of the illustrated in Fig. 3. Inmaking this assembly I prefer to apply stenciled-lines or zones ofadhesive to the marginal edges of the shell blank as shown at 10, Fig.2, although the same result may be secured by applying adhesive to themarginal edges of the cover blank. In some instances, as where so calledtight wrapped boxes are made I also apply adhesive to the underface ofthe shell blank, or the adhesive may be applied to the upper face of thecover blank, in order that the cover blank may be adhesively afiixedthroughout to the face of the shell blank. Ifso called loose wrapped'boxes are made, then I apply the adhesive only to the marginal edges ofthe box shell blank or to the marginal edges of the cover blank, one orthe other, as desired.

The assembly having been formed. the side wings thereof are folded up atright angles to the body portion to produce the structure illustrated inFig. 4 wherein it will be seen that the portions 8 of the side wings ofthe cover blank extend over onto and cover marginal edges of the cornerlaps 4 of the: shell blank. The end wings 3 of the shell blank are thenfolded up at right angles to the body portion, leaving the end wings ofthe cover blank free, as shown in Fig. 5. Then the partially coveredcorner laps of theassembly are infolded at right angles to the sidewings so as to cause por- 'tions 9* of the inturned marginal edges 9 tolie in between adjacent faces ofthe end wings 3 and orner laps-4 of theshell blank. as more clear ly shown in Fig. 6, thus providing neatlycovered corner oints at the points where the corner laps are bent orfolded and also providing a stronger corner joint construction. Inasmuchas the ends of the corner laps 4 are provided with adhesive, these lapsmay be readily and securely attached to the end wings 30f the shellblank when folded as described, suitable pressure being employed afterfolding the parts in order to securely retain them in position. Theassembly having been folded in the manner described and as illustratedin Fig. 6. the end wings 7 of the cover blank are then folded up so asto overlie and neatly cover the multiply end walls of the box as thusformed and the marginal edges ofthe said cover blank end wings areinturned 'over the marginal edges of the multiply \end walls of the boxand adhesively affixed to the inner face thereof to produce the finishedstructure illustrated in Fig. 9.

If tight wrapped boxes are being formed the end wings 7 of the coverblank will be adhesively attached to the outer face of the end walls ofthe box structure. but if loose wrapped boxes are being formed. then theend wings will simply overlie the outer face of the end walls, but ineither case the marginal edges of the end wings will overlie themarginal edges of the multiply end walls and will be adhesively attachedto the inner face of each end wall.

One of the distinguishing features of my improved box over all priorconstructions resides in the fact that the inturned marginal portions 9of the cover paper adjacent the corners of the box are confined be- I asillustrated in Fig. 3 of the accompanying drawings and then folding theassembly into box form as this procedure enables me to make the boxesmore expeditiously and more cheaply, although I do not wish to beunderstood as limiting myself to this exact procedure.

In the illustrated embodiment of my in vention I have shown the endwings 7 of the cover blank as having a single thick-,

ness width equal in width to their.com panion end wings 3 of the shellblank and I have also shownthe marginal extensions.

9 of the cover blank as terminating short of the extreme ends of thecorner laps 4, but I do not wish to be understood as confining myself tothis particular construction as the dimensions of the wrapper may bevaried somewhat without departing from the true spirit of the invention.a principal feature of which, as heretofore stated, resides in the factthat marginal portions of the cover blank lie in between adjacent facesof the multiply end walls of the folded box shell blank.

lVhile I have herein shown and described a preferred embodiment of myinvention, I do not wish to be understood as limiting myself to theprecise construction shown,

except as I may be limited by the terms of the appended claims and Ireserve the right to make such changes or additions in the structure asmay fairly fall within the terms of such claims and without departingfrom the true spirit of the invention.

I claim:

1. A covered paper box including a shell blank folded to box form andhaving multiply end walls formed in part by corner laps and in part byend wings, constituting portions of the shell blank. the said cornerlaps being arranged exteriorly of the end wings. and a cover blankapplied to the box and having-marginal edges thereof overlying themarginal edges of the side walls as well as the marginal edges of thefolded corner laps, portions of said overlying marginal edges carried bythe corner laps be ing confined between adjacent faces of the end wingsand their associated corner laps said cover blank also having end wingsfolded to overlie the outer. face and upper edges of each multiply endwall of the box with the marginal edge of each wing adhesively aflixedto the inner face of its com r panion shell blankend wing.
